How do you bleed air from the power steering rack 2001 ford focus se?

Make sure the reservoir is full of P/S fluid. Start the engine and using the line wrench, break the high-pressure line loose at the steering gear. If you are not sure which line is the high side, look at the Power Steering pump. The highest line that is held in by a flare nut is the high-pressure line. The lowest line is held in with a hose clamp and is the return line or low-pressure line. Run the engine and slowly open the high pressure fitting on the steering gear just until the fluid starts running out. Stop there and hold it open until nothing but fluid is coming out. Tighten the fitting. Now start the engine and turn the steering wheel as far to the right as you can and then turn it as far to the left as you can. Do this about 5 times. This should remove any air left in the system.
